Smart metering has gained considerable attention as a research focus due to its reliability and energy-efficient nature compared to traditional electromechanical metering systems. Existing methods primarily focus on data management,rather than emphasizing efficiency. Accurate prediction of electricity consumption is crucial for enabling intelligent grid operations,including resource planning and demandsupply balancing. Smart metering solutions offer users the benefits of effectively interpreting their energy utilization and optimizing costs. Motivated by this,this paper presents an Intelligent Energy Utilization Analysis using Smart Metering Data(IUA-SMD)model to determine energy consumption patterns. The proposed IUA-SMD model comprises three major processes:data Pre-processing,feature extraction,and classification,with parameter optimization. We employ the extreme learning machine(ELM)based classification approach within the IUA-SMD model to derive optimal energy utilization labels. Additionally,we apply the shell game optimization(SGO)algorithm to enhance the classification efficiency of the ELM by optimizing its parameters. The effectiveness of the IUA-SMD model is evaluated using an extensive dataset of smart metering data,and the results are analyzed in terms of accuracy and mean square error(MSE). The proposed model demonstrates superior performance,achieving a maximum accuracy of65.917% and a minimum MSE of0.096. These results highlight the potential of the IUA-SMD model for enabling efficient energy utilization through intelligent analysis of smart metering data.

Background and study aims: Although surgery remains the gold standard for the treatment of symptomatic common bile duct stenosis associated with chronic pancreatitis, plastic and self-expandable open-mesh stents have been proposed as alternative treatments. These may dysfunction, however, mainly due to stent occlusion by clogging or by hyperplasia of inflammatory tissue. The aim of this study was to evaluate the safety and long-term results of using partially covered metal stents in this setting. Patients and methods: A total of 14 patients (12 men, 2 women; mean age 50 ± 3 years) underwent partially covered metal stent insertion for common bile duct stenosis secondary to chronic pancreatitis (12 alcohol-related, two idiopathic). They had all been treated previously with plastic prostheses. results: Either a 40-mm (n = 13) or a 60-mm (n = 1) partially covered metal stent was placed, depending on the length of the common bile duct stenosis and the level of the cystic duct bifurcation. Stent placement was successful, with resolution of cholangitis and improvement in cholestasis, in all patients. During the median follow-up period of 22 months (range 12- 33 months)- seven patients developed dysfunction of the stent and required re-treatment. At 12, 24, and 30 months, the stent patency rates were 100% , 40% , and 37.5% respectively. Conclusions: While partially covered metal stenting is safe and effective for the initial treatment of chronic pancreatitis-associated common bile duct stenosis and shows promising short-term results, long-term data show that dysfunction occurs in 50% of cases. In light of the continued interest in nonsurgical treatment of this condition, further research is warranted to investigate new stent designs with improved long-term patency.

Background and Study Aims: Although it has been proved that pancreatic stentin g is effective in the symptomatic management of severe chronic pancreatitis, lon g-term outcomes after stent removal have not been fully evaluated. Patients and Methods: A total of 100 patients (75 men, 25 women; median age 49) with severe chronic pancreatitis and pancreatic duct strictures were successfully treated fo r pancreatic pain using polyethylene pancreatic stents and were followed up for at least 1 year after stent removal. The stents were exchanged “on demand" (in cases of recurrence of pain) and a definitive stent removal was attempted on the basis of clinical and endoscopic findings. Clinical variables were retrospectiv ely assessed as potential predictors of re-stenting. results: The etiology of t he chronic pancreatitis was alcoholic (77%), idiopathic (18%), or hereditary ( 5%). Patients were followed up for a median period of 69 months (range 14-163 months) after study entry, including a median period of 27 months (range 12 -12 6 months) after stent removal. The median duration of pancreatic stenting before stent removal was 23 months (range 2 -134 months). After attempted definitive stent removal, 30 patients (30%) required re-stenting within the first year of follow-up, at a median time of 5.5 months after stent removal (range 1-12 mon ths), while in 70 patients (70%) pain control remained adequate during that period. By the end of the follow-up period a total of 38 patients had require d re-stenting and four ultimately underwent pancreaticojejunostomy. Pancreas di visum was the only factor significantly associated with a higher risk of re-ste nting (P = 0.002). Conclusions: The majority (70%) of patients with severe chro nic pancreatitis who respond to pancreatic stenting maintain this response after definitive stent removal. However,a significantly higher re-stenting rate was observed in patients with chronic pancreatitis and pancreas divisum.

Background and study aims: Endoscopy workshops are thought to be associated with larger numbers of complications than routine clinical treatment. In this study, patients who underwent endoscopic retrograde cholangiopancreatography (ERCP) during live demonstrations were compared with matched patients treated in an ERCP unit. Patients and methods: Patients who underwent ERCP during workshops over a 12-year period were reviewed. The control for each patient was the next patient admitted to the same ERCP unit with similar indications. Possible delays before treatment, ERCP indications, the use of general anesthesia, standard endoscopic and special treatments, success and complication rates for ERCP, prolonged hospitalization periods, and financial benefits for patients were assessed. results: A total of 168 workshop patients and 168 control patients were compared. ERCP was delayed in 18 patients to allow treatment during the workshops. General anesthesia was used in 87.5% of the workshop patients, in comparison with 44% of the control patients (P re did not differ, and the endoscopic treatments carried out also did not differ significantly, with the exception of cholangiopancreatoscopy (7% in the workshop group versus 0% ; P re similar in the workshop and control patients, as was the duration of hospitalization. Among the patients treated during workshops, 45% benefited financially, as they were not charged for stents or other devices. Conclusions: These results suggest that, in this setting, ERCP performed during live demonstrations is safe and raises no major ethical problems.

The defining feature of a mass extinction and its associated recovery is the global amount of extinction that occurred[1]. However, there is finer-scale detail to the story, as seen in the ongoing modern mass extinction(the sixth mass extinction), which exhibits variable effects among marine ecosystems and environments, and hence geographic areas [1].

A strong motivation for studying mass extinctions is understanding how current climatic and biodiversity crises will affect creatures living on land such as ourselves. Perhaps the question is: how bad can it get? In that case, terrestrial Permian-Triassic mass extinctions are an irresistible worst-case scenario [1].

A recent study by Adams and colleagues published in Nature unveiled more than one hundred genes that are involved in micronucleus formation,1 which is a biomarker for genomic instability and associated with aging,cancer,and other disorders.2 As an outstanding achievement,the authors identified DSCC1(DNA replication And Sister Chromatid Cohesion 1)as a critical gene protecting against early developmental defects,genomic instability,reduced proliferative capacity,cohesinopathy-related phenotypes,and tumor development in vivo.
